Cabinet shapes

The only motto here is “Do what you like.” You don’t need to use the standard square box that everyone else has already. An unusual cabinet shape is not just an eye-catcher – it can also have tonal advantages. Cabinets with different-sized wall surfaces or walls that are not parallel tend to have fewer cabinet vibrations and standing waves inside the cabinet than square shapes – you just need to be able to build the cabinet.

For bass-reflex and closed boxes and related versions (e.g. the band-pass), a speaker that sounds the way it is supposed to depends on the cabinet volume. So if you want to change the shape or the wood thickness given in the construction plan, make sure you keep the same net volume. One “shot glass” more or less won’t make a difference – think about the reinforcement rings on the inside of the box! In designing the box, you should primarily think about your living situation; build a tall narrow box if that’s what fits, or a “fridge” if it will work better in the room.﻿

It may be true that the deflection behavior of the speaker chassis is related to the width of the baffle board; but it’s also true that these effects are more often measured than heard. In the frequency diagram, which is (usually) measured one meter away from the box, at the height of the tweeter, there are a few peaks and dips between 1000 Hz (baffle board about 60 cm wide) and 4000 Hz (baffle board about 12 cm wide); below an angle of 30 ° or at a greater distance from the box, these effects are less relevant. In narrower boxes, the sound-pressure gain in the mid-range, caused by reflections from the front, shifts slightly toward higher frequencies; in boxes that are wider than the construction specifications, the frequencies are slightly lower. The effects of the home installation site, which unfortunately are hard to change, have a much greater effect on your listening pleasure. If the bass speaker or the reflex opening is installed near ground level, it produces a louder but not necessarily better fundamental tone. In some constructions, this arrangement is chosen intentionally. Modifying the construction could also create this (un-)desirable effect. Of course, the connected amplifier electronics also have a much greater impact on how you enjoy music at home. If your speaker doesn’t sound good in your house, it probably has less to do with your cabinet design than with picking out the wrong speaker for your domestic and electronic situation.

For these reasons, we advise you to test out speakers at home before you buy them so that you won’t be disappointed later. A specialized retailer will be able to help you out.

You should not make any interior modifications in cabinets that use an integrated sound conductor for the bass transmission (e.g. transmission lines, horns). However, in these models you can give your creativity free rein with the exterior design.﻿
